My bike

I looked at those swing arms and I see that two different ones are offered. Both aluminum. One is built like the stock swing arm and the other (the one you have) has a lower brace (I think that's what it is) that hangs down below the main arms. What is the purpose of that? Does it keep the swing arm from twisting or is there another function? It looks trick but I'm sure there is more to it than that.

The bracing is used to reduce flex, much like a roof can be strengthened by adding a truss. I believe this swingarm is total overkill for the amount of power, and the intended use of this bike. But it sure looks cool!
...and I suppose I'm ready for that nitrous-super-turbocharging kit now!
